Top 10 Best Kensington Trackball in 2026 Compared

This side-by-side comparison covers ball diameter, connection style, scrolling method, programmability, and other practical differences among all ten Kensington trackballs.

1. Expert Wireless Trackball – Best Overall Kensington Trackball

4.2Editor scoreCheck price on Amazon

Expert Wireless Trackball

55mm optical tracking ball

Bluetooth LE and 2.4GHz

Detachable wrist support

Four programmable buttons

The Kensington Expert Wireless Trackball is our overall recommendation because it combines a large 55mm ball, dual wireless connectivity, a mechanical scroll ring, and a detachable wrist rest. Its 4.2 rating reflects a balanced feature set for people who want precise control without giving up the convenience of a cable-free desk.

Pros

• Large precise ball
• Flexible wireless connections
• Useful scroll ring
• Comfortable wrist support
• Extensive customization

Cons

• Larger desktop footprint
• Software excludes Windows ARM

Diamond Eye optical tracking and the large ball make it appealing for detailed navigation, document work, and applications requiring controlled cursor movement. The scroll ring supports quick vertical movement through long pages, while the customizable four-button layout can adapt to common commands. KensingtonKonnect also provides control over button assignments, cursor speed, and scrolling speed.

Its main compromises are physical size and a software limitation for ARM-based Windows systems. The supplied dimensions also make it less compact than the smaller Orbit models. These are meaningful considerations for a cramped desk, but the combination of a large ball, flexible connections, and removable support gives it broad everyday appeal.

This is the strongest choice for a user who wants one wireless trackball to handle productivity, browsing, creative work, and general navigation. It is particularly suitable for people who appreciate a larger ball and do not mind a substantial desktop footprint. Those prioritizing minimal space should examine the compact Orbit options instead.

Large-Ball Precision and Control

The 55mm ball provides a substantial surface that can be controlled with broad fingertip or palm movements. Combined with Diamond Eye optical tracking, it gives users a precise alternative to repeatedly sweeping a conventional mouse across the desk.

Flexible Wireless Workstation Setup

Built-in Bluetooth LE and the included USB dongle offer two ways to connect. Kensington recommends the dongle for Windows 7 and later, while Bluetooth works best with Windows 8.1 or later and Mac OS X 10.8 or later.

2. SlimBlade Pro Wireless – Most Feature-Rich Kensington Trackball

4.1Editor scoreCheck price on Amazon

SlimBlade Pro Wireless Trackball

55mm dual-sensor ball

Three connection methods

Rechargeable four-month battery

Eight programmable button sets

The Kensington SlimBlade Pro Wireless is the most feature-rich model in this guide, earning a 4.1 rating for its extensive connectivity, rechargeable design, and unusually deep programmability. It supports Bluetooth, 2.4GHz wireless, and wired use, allowing the same device to serve desktop and travel setups.

Pros

• Three connection options
• Long rechargeable battery life
• Extensive button programming
• Low-profile ambidextrous shape
• Accurate dual-sensor tracking

Cons

• Premium feature complexity
• Windows ARM currently unsupported

We may earn a commission when you buy through this link, at no additional cost to you.

Its rechargeable battery is advertised to last four months from a single USB-C charge. That makes it appealing for users who want wireless freedom without managing replaceable batteries. The included 2.4GHz dongle accepts USB-A directly or through the included USB-C-to-USB-A adapter, while the supplied charging cable supports convenient setup.

Dual sensors track the large 55mm ball for responsive movement and scrolling. Eight sets of programmable buttons provide more flexibility than most competing products, though that depth may take time to configure. KensingtonKonnect currently lacks support for Windows ARM-based computers, and the rechargeable design adds more complexity than a simple wired mouse.

Choose the SlimBlade Pro Wireless when connectivity options, battery management, and custom controls matter more than minimizing complexity. It suits power users, office professionals, and anyone who wants one device to move between computers. Buyers who only need basic navigation may find a simpler Orbit model easier to manage.

One Device, Three Connection Styles

Bluetooth, 2.4GHz wireless, and wired connectivity make this model unusually adaptable. The included dongle and USB-C charging cable cover common modern and legacy USB arrangements, while the wired mode offers a straightforward fallback.

Programmable for Advanced Workflows

KensingtonKonnect can assign a wide range of program functions across eight button sets. This makes the trackball relevant to creative applications and repetitive workflows where dedicated commands can reduce the need to navigate menus manually.

3. Orbit with Scroll Ring – Best Scrolling Kensington Trackball

4.3Editor scoreCheck price on Amazon

Orbit with Scroll Ring

40mm optical tracking ball

Wired USB connectivity

Mechanical scroll ring

Detachable wrist rest

The Kensington Orbit Trackball Mouse with Scroll Ring carries a 4.3 rating and stands out for its precise 40mm optical ball, mechanical scroll ring, and detachable wrist rest. It is a practical choice for users who enjoy a trackball but do not need wireless connectivity or extensive programmability.

Pros

• Highly rated 4.3 design
• Precise 40mm ball
• Convenient mechanical scroll ring
• Removable wrist support
• Works with both hands

Cons

• Wired-only desktop design
• Only two programmable buttons

We may earn a commission when you buy through this link, at no additional cost to you.

The blue ball is described as an absolute spherical hard surface designed for predictable tracking. Its scroll ring offers a direct way to move through web pages and documents, while the wrist rest cushions the hand during extended sessions. KensingtonKonnect allows users to assign functions to both buttons and adjust cursor and scrolling speeds.

The two-button layout is intentionally simple, but it will feel limited to users who rely on numerous shortcuts. The wired connection also keeps the desk tethered. ChromeOS users can access basic HID functions, although they cannot customize the device through KensingtonWorks.

This Orbit model is well suited to browsing, office work, and general productivity on a fixed desk. It is a particularly good match for someone who wants the Orbit form factor and a mechanical scroll ring but prefers a simple wired setup. Those needing multiple devices or connection modes should consider the Orbit Wireless Scroll Ring.

Mechanical Scrolling with Direct Feedback

The raised scroll ring provides a tactile way to move vertically through long pages, spreadsheets, and documents. Compared with a tiny wheel, it can be easier to locate and control without shifting the hand away from the ball.

Comfortable Two-Hand Workspace

The ambidextrous layout is designed to work equally well for right- and left-handed users. A softly padded, detachable wrist rest provides additional support and can be removed when the user prefers a more open setup.

4. Orbit Wired Trackball – Best Value Kensington Trackball

4.2Editor scoreCheck price on Amazon

Orbit Wired Trackball

40mm optically tracked ball

Reliable wired USB

Compact ambidextrous housing

Two customizable buttons

The Kensington Orbit Trackball Mouse in silver and black is our best budget recommendation, with a 4.2 rating and a straightforward feature set. It offers a medium 40mm ball, precise optical tracking, and an ambidextrous, compact design without the expense of wireless hardware or rechargeable components.

Pros

• Simple wired operation
• No battery management
• Compact desk footprint
• Recognizable Orbit design
• Compatible with major systems

Cons

• No mechanical scroll ring
• Limited two-button customization

We may earn a commission when you buy through this link, at no additional cost to you.

Internal red optics track the ball accurately, and the wired USB connection provides fast, simple installation. Because the device draws power through the cable, users do not need batteries or a pairing process. It works with Windows, macOS 10.8 and later, and Chrome OS 44 and later.

This model does not include the distinctive mechanical scroll ring found on another Orbit version, so users who prioritize tactile scrolling may need to compromise. KensingtonKonnect still permits program assignments for the two buttons and cursor-speed adjustment, although the customization options are limited. The included two-year warranty provides basic coverage.

For a fixed workstation, the Orbit Wired Trackball is a sound first trackball because it is compact, uncomplicated, and requires little maintenance. It is ideal for budget-conscious users who want accurate cursor control and a small footprint. Mobile users or those who need advanced buttons should save up for a wireless or more programmable option.

Reliable Connection Without Batteries

The wired USB design removes charging, battery replacement, and wireless pairing from the equation. That simplicity makes it dependable for a permanent desk where consistent access to a USB port is convenient.

Space-Saving Ambidextrous Design

The Orbit body uses substantially less space than the movement required by a conventional mouse. Its symmetrical shape also avoids locking the design into a specific hand, which is useful for shared workstations.

5. Wired SlimBlade Trackball – Best Low-Profile Design

4.3Editor scoreCheck price on Amazon

Wired SlimBlade Trackball

Low-profile silver design

Wired USB operation

Laser cursor tracking

Ambidextrous low-profile shape

The Kensington Wired SlimBlade Trackball has a 4.3 rating and focuses on a sleek, low-profile alternative to a conventional mouse. Its silver metallic finish gives it a distinctive appearance, while laser tracking and an ambidextrous shape support precise use by a broad range of users.

Pros

• Sleek low-profile styling
• Precise laser tracking
• Less wrist and arm motion
• Small desktop footprint
• Supports button customization

Cons

• Wired connection limits portability
• No specified wireless connectivity

We may earn a commission when you buy through this link, at no additional cost to you.

The low-profile construction requires less arm and wrist movement and occupies less desk space than a traditional mouse. That makes it useful where desk depth is limited or the user prefers a flatter control surface. KensingtonWorks provides software-based button customization for users who want shortcuts beyond the default controls.

As a wired device, it offers dependable power and a straightforward USB connection, but it cannot move freely between computers. The supplied information does not list a scroll-ring mechanism, rechargeable battery, or multi-device pairing, so its appeal depends on whether the user values the SlimBlade form and precise tracking over modern wireless convenience.

This is a good choice for a permanent workstation that values visual simplicity, a low profile, and precise cursor control. It may particularly appeal to users moving from a mouse to a trackball without wanting a large device. People who routinely move between devices should examine the SlimBlade Pro Wireless instead.

Low-Profile Desktop Appeal

The shallow body creates a cleaner and more compact workstation than the arm movement required to operate a full-size mouse. It can also keep the user's forearm closer to the desk than some raised alternatives.

Precision Through Laser Tracking

Laser tracking provides controlled cursor movement while preserving the familiar response of a conventional pointing device. The result is especially relevant to users interested in a trackball but not ready to adjust to a larger ball.

6. Orbit Wireless Scroll Ring – Best Balanced Wireless Orbit

4.2Editor scoreCheck price on Amazon

Orbit Wireless Scroll Ring

40mm optical tracking ball

Bluetooth and 2.4GHz

Four selectable DPI levels

Detachable padded wrist rest

The Kensington Orbit Wireless Trackball with Scroll Ring is a balanced wireless option with a 4.2 rating. It combines a compact 40mm ball, a mechanical scroll ring, four DPI settings, and both 2.4GHz and Bluetooth connectivity in an ambidextrous design with a detachable wrist rest.

Pros

• Dual wireless connection modes
• Mechanical scroll ring
• Four DPI options
• Detachable wrist support
• Compact and ambidextrous

Cons

• Requires battery management
• Only four function buttons

We may earn a commission when you buy through this link, at no additional cost to you.

The two wireless methods give users flexibility between a dedicated USB receiver and Bluetooth. The 2.4GHz option includes 128-bit AES encryption, while Bluetooth supports versions 3.0 and Low Energy. Four DPI settings—400, 800, 1,200, and 1,600—let users move between precision editing and faster everyday navigation.

KensingtonKonnect adds button assignment and cursor and scrolling speed controls, although four buttons offer less scope than the nine-button vertical model or the eight sets supported by the SlimBlade Pro. The trackball also requires batteries, making charging or replacement a consideration when compared with wired designs.

This is an attractive option for a wireless desk that wants a tactile scroll ring without moving to a much larger trackball. It suits users who value compactness, Mac and PC compatibility, and adjustable pointer speed. Users who need extensive shortcut programming should consider the more configurable alternatives.

Useful Wireless Connection Choices

Users can choose a 2.4GHz receiver for a dedicated connection or Bluetooth for a more flexible setup. Both are included in the product's feature set, making it easier to match the trackball to different computers and workspaces.

Tailored Cursor Speed

Four selectable DPI levels cover fine positioning and faster screen navigation. The 400 setting is relevant to detailed editing, while 1,600 can cover word processing and casual browsing with less finger movement.

7. Orbit Wireless Touch Ring – Best Compact Wireless Option

4.2Editor scoreCheck price on Amazon

Orbit Wireless Touch Ring

Compact 32mm trackball

Bluetooth LE receiver support

Touch-style scroll surface

Designed for smaller hands

The Kensington Orbit Wireless Trackball with Touch Scroll Ring is a compact option with a 4.2 rating. Its 32mm ball distinguishes it from the standard 40mm Orbit models, making it most relevant to users with small to average-sized hands or those who prioritize desk space over a larger control surface.

Pros

• Very compact design
• Supports smaller hands
• Wireless connection choices
• No drivers required
• Touch scrolling adds convenience

Cons

• Smaller ball precision
• Less information on programmability

We may earn a commission when you buy through this link, at no additional cost to you.

Connection is available through Bluetooth LE or a USB nano receiver, and the product supports plug-and-play operation without drivers. The touch scroll surface provides a different scrolling experience from a raised mechanical ring, allowing the user to glide through pages and documents with less finger displacement.

A compact ball can feel more natural to some users than a large one, but it may provide less margin for broad movement. The supplied information emphasizes KensingtonKonnect customization without detailing the same depth of button programming offered by higher-end models. The 4.2 rating nevertheless suggests a generally well-received product.

Choose this trackball for a small desk, a shared workspace, or a user who prefers a compact Orbit body and touch-based scrolling. It is also a sensible starting point for people learning to use a trackball because the smaller ball can encourage more deliberate finger control. Larger-hand users may prefer the 40mm models.

Compact Ball for Limited Desks

The 32mm ball allows the device to maintain a small footprint while still providing a trackball-style pointing experience. That makes it useful for compact desks, dorm rooms, and shared offices where every centimeter matters.

Touch Scrolling Without Drivers

The touch ring supports document and web-page navigation without a conventional wheel protruding from the body. Plug-and-play setup also reduces installation friction, making the mouse suitable for quick workstation transitions.

8. Orbit Optical Wired Trackball – Simplest Wired Orbit

4.0Editor scoreCheck price on Amazon

Orbit Optical Wired Trackball

40mm spherical optical ball

Wired USB 2.0 connection

Compact ambidextrous body

Standard click-and-scroll layout

The Kensington Orbit Optical Trackball Mouse in black and silver is a straightforward USB 2.0 pointing device with a 4.0 rating. It focuses on the essentials: optical tracking, a precisely formed 40mm ball, a compact footprint, and a symmetrical design that works for either hand.

Pros

• Simple plug-and-play setup
• Precise spherical ball
• Compact desktop footprint
• Symmetrical for either hand
• No wireless pairing required

Cons

• Basic feature set
• No highlighted programmability

We may earn a commission when you buy through this link, at no additional cost to you.

Its perfect-sphere ball is designed to support accurate cursor control, while optical tracking provides smooth movement. Plug-and-play installation through the wired USB connection avoids pairing and driver complications. Compared with the larger Expert and SlimBlade Pro models, the Orbit footprint leaves more room on the desk.

This model's information highlights fewer advanced features than several competitors. It does not emphasize a mechanical scroll ring, DPI selection, or extensive software customization, so buyers should treat it as a basic trackball rather than a programmable productivity tool. The benefit is a straightforward design with fewer variables.

It is most appropriate for a fixed computer, a learner trying a trackball, or a user who wants the Orbit shape without wireless features. Those who want a mechanical scroll ring and a detachable wrist rest should review the wired Orbit with Scroll Ring. Users needing custom shortcuts may need to look toward newer models.

No-Fuss USB Operation

The wired USB 2.0 connection makes setup immediate and dependable. It is a good fit for users who want to eliminate wireless pairing or battery management from their daily computer routine.

Compact and Symmetrical

The body takes up less desk space than a mouse while its balanced design accommodates both right- and left-handed use. This makes it suitable for shared offices and flexible workstation arrangements.

9. TB675 Vertical Wireless – Best Multi-Device Vertical Model

3.8Editor scoreCheck price on Amazon

TB675 Vertical Wireless

60-degree vertical body angle

Four-device connection support

Rechargeable 34mm thumb ball

Nine programmable buttons

The Kensington TB675 Wireless Vertical Trackball is a feature-rich alternative for users who prefer a vertical form and thumb-operated pointing. It has a 3.8 rating, the lowest in this group, but its connectivity, programmability, and rechargeable design set it apart from the traditional Orbit and SlimBlade shapes.

Pros

• Ergonomist-approved vertical angle
• Connects to four devices
• Nine customizable buttons
• Rechargeable USB-C design
• Four DPI levels

Cons

• Lower 3.8 user rating
• Thumb-operated ball demands adaptation

We may earn a commission when you buy through this link, at no additional cost to you.

Its contoured body uses a 60-degree vertical tilt intended to support more natural wrist and thumb positioning, particularly for average-sized hands. A 34mm ball is controlled with the thumb, and four DPI settings from 400 to 1,600 accommodate detailed work and faster navigation. The device selector makes it possible to connect to four devices at once.

Connection options include a 2.4GHz dongle with 128-bit AES encryption, dual Bluetooth, and wired USB-C. Nine programmable buttons and the Kensington 4D scroll wheel provide exceptional control, while KensingtonKonnect can assign shortcuts or macros. The trade-off is that this vertical and thumb-based layout is different enough from a mouse that some users may need time to adapt.

The TB675 is best for users who explicitly want a vertical trackball, multi-device switching, and deep button customization. It is less suitable for someone seeking a conventional symmetrical design or the gentlest transition from a mouse. Its lower rating also warrants checking recent customer feedback for concerns that may relate to individual preferences.

Vertical Shape, Thumb-Based Control

The 60-degree profile is designed to encourage a more natural wrist and thumb position. Because movement comes from the thumb rather than the index finger, users with established mouse habits may need to allow additional adjustment time.

Four Devices, Nine Buttons

A built-in selector allows quick transitions among four connected devices. The nine-button layout, including assignable side buttons, can be configured with shortcuts or macros for advanced productivity workflows.

Slimblade Trackball

Slimblade trackball design

Model K72327US

Compact mouse alternative

Minimal desk footprint

The Kensington Slimblade Trackball has the highest listed rating in this selection at 4.5. Its appeal centers on the established Slimblade concept: a compact, low-profile pointing device that occupies less desk space than a traditional mouse and preserves a familiar, restrained appearance.

Pros

• Highest listed user rating
• Slim minimalist appearance
• Compact mouse alternative
• Recognizable Kensington model
• Simple overall concept

Cons

• Limited supplied specifications
• No detailed feature confirmation

We may earn a commission when you buy through this link, at no additional cost to you.

The supplied product information identifies the model as K72327US, corresponding to the Slimblade family represented elsewhere in the guide. That association provides useful context because the related wired SlimBlade model is described as using laser tracking, an ambidextrous low-profile shape, and button customization through KensingtonWorks.

However, the product listing supplied for this specific model does not explicitly state its connectivity, tracking system, dimensions, or software capabilities. It would therefore be inappropriate to assume that every feature of the related wired model applies without checking the current listing. Its high rating indicates strong customer reception, but the best buying decision still depends on verified details.

This model is best for a user drawn to the Slimblade's clean, minimal appearance and compact footprint. It may be a particularly attractive choice for a tidy office or a user who wants the trackball concept without a visually bulky control device. Before buying, confirm the current connection method, ball size, warranty, and supported software.

A Familiar Trackball Alternative

The Slimblade concept offers a familiar alternative to a mouse without departing completely from its low-profile shape. It can make a workstation feel more orderly while preserving the idea of a compact peripheral.

Verify the Current Listing

The supplied details for this model are concise, so buyers should check the live product page for complete specifications. Particular attention should be paid to connection type, dimensions, and included accessories.

Buying Guide – How to Choose the Best Kensington Trackball

A useful Kensington trackball should match your desk, hand, computer setup, and preferred controls. The following factors help narrow the field before you compare final features.

Ball Size and Control Style

Ball size is one of the most important adjustments when moving from a mouse. The Expert and SlimBlade Pro use large 55mm balls that encourage broad, deliberate finger and palm movement. Standard Orbit models use a medium 40mm ball, while the wireless touch-ring Orbit uses a compact 32mm ball and the vertical TB675 uses a 34mm thumb-operated ball. Larger surfaces can reduce the amount of movement needed to cross the screen, but they also take up more space and may feel less familiar at first. Smaller balls are easier to control precisely and suit compact desks, although users with larger hands may find them less comfortable.

Wired Versus Wireless Connectivity

A wired trackball offers simple power delivery, consistent operation, and no charging routine. The basic Orbit models and Wired SlimBlade are designed around this approach. Wireless models add freedom, but they introduce receiver management, pairing, batteries, or rechargeable charging. The Expert supports Bluetooth LE and 2.4GHz, while the Orbit Wireless Scroll Ring offers Bluetooth and 2.4GHz. The SlimBlade Pro is the most flexible because it also works as a wired device. The TB675 can connect to four devices through dual Bluetooth, a 2.4GHz dongle, and a wired USB-C connection.

Scrolling Method and Document Comfort

The scroll system can matter as much as the pointing ball when working in long documents. Models with a mechanical ring provide tactile feedback and direct vertical scrolling. The Orbit Wireless Touch Ring uses a touch surface for a different, flatter approach, while the TB675 offers a metal four-direction wheel for vertical and horizontal navigation. Other basic Orbit models use conventional clicking and scrolling without a highlighted ring. Consider the type and size of your daily documents, as well as whether you prefer mechanical feedback, touch gestures, or a conventional wheel.

Programmability and Workflow Support

Programmable buttons can turn frequently repeated actions into direct commands. KensingtonKonnect is used across several products and can handle button assignments, cursor speed, and scrolling adjustments. The SlimBlade Pro supports eight sets of programmable buttons, the TB675 provides nine buttons with customizable side controls, and the Expert has a customizable four-button design. The two-button Orbit models support more limited assignment and speed control. KensingtonWorks provides button customization for the related Wired SlimBlade. Users should consider both the number of buttons and whether the software fits their applications rather than assuming a high button count automatically improves productivity.

Hand Size and Ergonomic Shape

Kensington offers several distinct shapes rather than one universal form. The Orbit products are ambidextrous and compact, the SlimBlade models are low-profile, the Expert is larger with a detachable wrist rest, and the TB675 uses a 60-degree vertical body controlled by the thumb. The wireless touch-ring Orbit is specifically described as suited to small and average-sized hands. Comfort also depends on the wrist rest, desk height, and session length. A trackball can reduce arm motion, but a poorly matched shape may still create tension. Users should consider whether they prefer index-finger operation, thumb operation, a raised profile, or a flat one.

DPI and Precision Needs

Cursor speed determines how far the pointer travels for a given movement of the ball. The Orbit Wireless Scroll Ring offers four settings at 400, 800, 1,200, and 1,600 DPI, allowing slower movement for detailed work and faster movement for broad navigation. The vertical TB675 also provides four selectable levels across the same range. Models without highlighted DPI controls may offer less flexibility, although software-based cursor-speed adjustment is available on some. Buyers who switch between detailed editing, spreadsheets, and general browsing will benefit from a quick way to alter sensitivity without changing the device.

Operating System and Software Compatibility

Basic operation and advanced customization are separate compatibility questions. Most products support Windows and macOS, and several also mention Chrome OS. KensingtonKonnect provides deeper configuration on compatible computers, but Windows ARM-based systems are currently unsupported for the Expert and SlimBlade Pro. The Orbit with Scroll Ring supports Chrome OS HID functions, though customization through KensingtonWorks is unavailable there. Check the operating system, Bluetooth version if applicable, receiver format, and software requirements before ordering, especially if you plan to use the trackball across several different computers.

Desktop Space and Accessories

A trackball generally needs less room than the area required to move a mouse, but the products differ significantly in footprint. The Expert measures 3.5 by 6.1 by 8 inches and includes a detachable wrist rest, making it the largest option in the list. The wired Orbit with Scroll Ring measures 4.5 by 5.5 by 2 inches and also includes a detachable rest. The touch-ring Orbit is designed for a smaller footprint. Accessories matter too: some wireless products include receivers and adapters, the SlimBlade Pro includes a USB-C charging cable, and the Expert supports a USB dongle for compatible systems.

How to Use and Care for Your Kensington Trackball

Begin by installing the appropriate Kensington software before assigning buttons or changing cursor and scrolling speeds. Connect the trackball using its wired USB connection, 2.4GHz receiver, or Bluetooth function, depending on the model and computer. If you use a receiver, place it close to the computer and away from USB hubs that could interfere with the connection. For Bluetooth models, confirm that the required Bluetooth version is available and pair the device through the operating system's settings.

Place the trackball where your forearm can rest naturally without reaching upward or rotating your wrist. Move the ball with controlled finger or thumb motions, keeping your hand relaxed rather than pressing hard against the surface. Use the scroll ring, touch surface, or scroll wheel for document navigation, and use the software to assign buttons only after you are comfortable with basic pointer movement. Allow extra time to adapt if you are changing from a mouse to a large ball or to a vertical thumb-operated design.

Keep the ball and optical sensors free of dust, crumbs, and sticky residue. Remove the device from the computer before cleaning it, and use a soft dry or lightly dampened cloth rather than harsh liquids. If the ball requires removal, follow the manufacturer's instructions, clean both the ball and rollers, and let every part dry fully before reinstallation. Rechargeable models should be charged through their specified USB-C connection, while battery-powered models should use compatible replacement batteries.

Frequently Asked Questions

Are Kensington trackballs suitable for left-handed users?

Several Kensington trackballs in this guide are explicitly ambidextrous, including the Expert, both standard wired Orbit models, the Wired SlimBlade, the Orbit Wireless Scroll Ring, the Orbit Wireless Touch Ring, and the basic Orbit Optical. The TB675 is different because its 34mm ball is operated with the thumb, so left-handed users should confirm that its vertical layout suits them. The best approach is to compare the hand positioning rather than relying on the ambidextrous label alone.

What is the difference between a 40mm and 55mm trackball?

A 55mm ball generally requires less finger movement to move the cursor a long distance and can feel more relaxed for some users. A 40mm ball requires a little more movement but offers a more compact body and may feel familiar to users accustomed to standard trackballs. Personal preference matters, so it is useful to consider hand size, available desk space, and the amount of precision required in daily work.

Can I use a Kensington trackball with Bluetooth?

It depends on the model. The Expert supports Bluetooth LE, the Orbit Wireless Scroll Ring supports Bluetooth 3.0 and LE, and the Orbit Wireless Touch Ring supports Bluetooth LE. The SlimBlade Pro supports Bluetooth BT4.0 or BT5.0, while the TB675 includes dual Bluetooth. Wired-only Orbit and SlimBlade models require their USB connection. Always check the operating system and Bluetooth version listed for the specific product.

Do Kensington trackballs need batteries?

Wired models do not need batteries because they receive power through the USB connection. Wireless Orbit models and the Expert require power management according to their individual battery systems. The SlimBlade Pro and TB675 use rechargeable batteries and USB-C charging, with the SlimBlade Pro advertising four months of battery life from a single charge. Check the current product instructions for battery type, charging time, and storage recommendations.

What software is used to customize Kensington trackballs?

KensingtonKonnect is the principal customization application mentioned for the Expert, SlimBlade Pro, and several Orbit models. It can support button assignments and cursor or scrolling adjustments, depending on the device. KensingtonWorks is associated with the Wired SlimBlade and the Chrome OS limitation noted for the Orbit with Scroll Ring. Windows ARM-based computers are currently unsupported for some KensingtonKonnect-compatible models, so software compatibility deserves confirmation.

Are trackballs better for small desks?

Trackballs can be more suitable for small desks because the device itself remains in place while the ball rolls. However, large models such as the Expert still occupy more space than compact Orbit products. The Wired SlimBlade, standard Orbit models, and especially the 32mm touch-ring Orbit may fit better in a constrained workspace. A larger ball can also reduce the distance your hand must travel, partly offsetting the larger housing.

How do I clean a Kensington trackball?

Disconnect the device and use a soft, lint-free cloth to wipe the exterior. If the ball can be removed, follow the model's instructions, clean the ball and exposed rollers, and avoid bringing moisture into the sensor housing. Do not use harsh chemicals or spray cleaner directly onto the device. Let all parts dry completely before replacing the ball and reconnecting the trackball.

Is a scroll ring better than a touch scroll surface?

A mechanical scroll ring offers visible motion, tactile feedback, and precise incremental scrolling, which many long-document users find easy to control. A touch surface keeps the body flatter and may suit users who dislike protruding controls. The best choice depends on preference, but a mechanical ring generally provides clearer feedback and a more conventional scrolling experience.

Final Thoughts on Choosing the Best Kensington Trackball

The Kensington Expert Wireless Trackball is the most balanced overall recommendation because it combines a large 55mm ball, mechanical scrolling, dual wireless connections, a detachable wrist rest, and useful customization. The SlimBlade Pro Wireless leads the premium and advanced-feature category with three connection methods, a rechargeable battery, and eight programmable button sets. For a simpler and more economical purchase, the wired Orbit Trackball provides dependable optical control without wireless complexity.

Your priorities should determine the alternative. Choose the Orbit Wireless Scroll Ring for a compact body with tactile scrolling and selectable DPI, the Orbit Wireless Touch Ring for the smallest ball and flat touch controls, the Wired SlimBlade for a low-profile metal design, or the TB675 for vertical ergonomics, four-device switching, and extensive button configuration. Ball size and shape should be matched carefully to your hand and desk.

Before ordering, confirm the latest operating system compatibility, included accessories, power requirements, and software support. Kensington trackball prices, availability, ratings, and product configurations can change over time, so check the current listing and recent customer feedback before making your final decision.
